Commit 6175ddf06b6172046a329e3abfd9c901a43efd2e changes the way
memcpy_toio() works for x86_64, causing firmware loading to fail for
some Ralink WLAN devices with the rt2800pci driver since linux 2.6.34.
This causes the log message: "phy0 -> rt2800pci_load_firmware: Error -
PBF system register not ready.".

Fix this by using __iowrite32_copy instead of memcpy_toio().
